On Sunday, July 31, 2011, when Expedition 28 astronaut Ron Garan aboard the International Space Station looked out his window, this is what he saw: the moon in this space wallpaper.And, he saw it 16 times. Said Garan, "We had simultaneous sunsets and moonsets." For Garan and the rest of the station crew, this extraordinary event is a daily occurrence. Since the station orbits the Earth every 90 minutes, each day the crew experiences this about 16 times a day.
